UniFit Continuous Packed Membrane Filter
Cobetter UniFit continuous packed MCE gridded membrane filters are sterile-sealed in individual bags on a continuous band, provide the user with the same quality and reliability as Cobetter MicroDisc individually packed MCE membranes.
It revolutionize filter handling by combining the benefits of ready-to-use, individually-packed membranes with a handling Dispenser. Just press the lever or button of the dispenser, the sterile membrane will be unwrapped from the package for easy access.
The pleating package of the band units ensures the membrane remain in perfect flat form when dispensed.

Features and Benefits
- Nictrocellulose mixed ester, biological inert mixture of cellulose acetate and cellulose nitrate.
- Outstanding bacterial recovery rates as microbial testing membrane.
- Rapid flow rate and high throughput contribute to consistent and uniform test results.
- Each continuous band contains 150 pcs of 47mm sterile, gridded filters.
- The folded bands provide hands-free convenience for the use of MCE microbiological analysis membrane, reduce laboratory time and boost lab efficiency.
- Gamma Irradiation meet to Sterility Assurance Level (SAL) of 10-6 as defined in ISO 11137-1:2006.
- Visible traceability, part number, lot number, pore size as well as sequential number (from 1 to 150) are printed clearly on the protective film of every membrane cell.
- Membranes numbered from 1 to 150, maintain control of the ribbon progressive usage.
- The folded ribbons provide hands-free convenience, reduce laboratory time and boost lab efficiency.
- Compatible with various dispensers, such as Millipore EZ-Pak Dispenser Curve, Sartorius Microsart E-Motion, Whatman Membrane-Butler.
- Easily peeling off the transparent film on the band, contribute smooth running on standard dispensers. Peeling Strength Verification Report.
